1 Claim. (01. 238-285) The present invention relates to new and useful improvements in railroad ties and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising novel means: for firmly securing the rails without the necessity of using the usual spikes.

Another very important object of the inven tion is to provide a railroad tie of the character described comprising wooden cushion blocks for the rails, together with novel means for retaining said blocks in position.

Other objects of the invention are to provide a railroad tie of the aforementioned character which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a. view in side elevation of a railroad tie constructed in accordance with the present invention, showing a pair of rails mounted thereon.

Figure 2 is a top plan View of one end portion cf-the invention.

Figure 3 is an end elevationalview.

Figure 4 is a view in side elevationof one end portion of the tie.

Figure 5 is a top plan view of one of the clamps.

Figure 6 is a detail view in side elevation of one of the clamps.

Figure 7 is a detail view in perspective of one of the bars to which the clamps are secured.

Figure 8 is a perspective View of one of the wooden cushion blocks.

Figure 9 is a View in side elevation of the tie plate.

Referring now tothe drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a tie of suitable metal or other material which is designated generally by the reference numeral 1. Of course, the tie i may be of any desired dimensions. The tie i has formed in its ends and at an. intermediate point pockets 2 for the reception of ballast to assist in retaining the tie against movement on the road bed. The pockets 2 also reduce the weight of the tie as well as the material therein.

The end portions of the tie I have formed therein transversely extending recesses 3 for the reception of wooden cushion blocks 4. Communicating with the recesses 3 in the vertical side walls thereof are substantially T-sha'ped channels 5. The horizontal portions of the channels 5 are for the reception of tongues 6 which are integral 5 with the blocks i. Thus, the blocks 5 are prevented from pulling up out of the recesses 3. It may be well to here state that the blocks 4 are slipped laterally into the recesses 3, the tongues 6 sliding in the channels 5. 10

Mounted in the vertical or head portions of the substantially T-shaped channels 5 are metallic bars I the ends of which project beyond the sides of the tie l. The projecting end portions of the bars 1 are provided with openings 8. The ref- 15 erence numeral i5 designates a pair of rails which are mounted on the blocks 4. Interposed between the bases of the rails 9 and the blocks 4 are plates It. The plates it comprise inwardly extending flanges ll on their outer ends engaged over the 20 outer portions of the rail bases and terminating in upstanding lips l2 which are adapted to abut the webs of said rails on the outer sides thereof. The rails. is are secured in position through the medium of pairs of crossed, substantially U- 25 shaped metallic clamps l3 having threaded end portions extending through the openings 8 in the bars. I and secured by nuts I l. The clamps l3 comprise bent or folded back intermediate or b ight portions constituting rail securing hooks i5. 30 The construction of the clamps I3 is shown to advantage in Figs. 5 and 6 of the drawings. One clamp of each pair is narrower than the other in order to pass betweenthe legs thereof. Also, one clamp of each pair is engaged at l5 directly with the inner portion of the rail base while the other clamp of each pair is engaged on the flange II of the plate lll closely adjacent the lip I2.

Thus, the clamps l3, in addition to anchoring the rails 9, also constitute means for retaining the blocks 4 andthe plates l8 in position.

It is thought that the manner in which the invention functions will be; readily apparent from a consideration, of the foregoing. Of course, the pairs of clamps. 13 hold the rails 9 in position on the ties l. The construction and arrangement is such that the blocks 4 may yield sufiiciently to cushion the rails. The ties l are first laid on the road bed and the blocks 4, also the bars 1 are inserted. Or, if desired,.these members may 50 have been mounted in position before the ties are transported to the desired location. The rails 9 are then placed in positionacross the blocks 4 and the plates H! are then driven into position beneath said rails. The clamps I3 are then ap- 55 plied. It will also be observed that the pairs of anchoring clamps I3 cross beneath the rails 9.

It is believed that the many advantages of a railroad tie constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A railroad tie of the class described having transversely extending recesses in its end portions and further having substantially T-shaped channels in the vertical side walls of the recesses, cushion blocks mountedin the recesses and including projecting tongues engaged in the adjacent portions of the channels, transversely extending bars mounted in the remaining portions of the channels and projecting beyond the sides of the tie, and pairs of crossed, substantially U-shaped clamps having their end portions secured to the projecting end portions of the bars, said clamps straddling the blocks and including substantially hook-shaped intermediate portions engageable with the rails for securing said rails in position on the blocks.
